CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 281,983, dated July 24,1883.

Application filed January 4, 1883. (No model.)

To all whom it may concern Be it known that 1, ROBERT H. DOWLING, acitizen of the United States, residing at Newark, in the county ofLicking and State of Ohio, have invented certain new and usefulImprovements in Car-Couplings; and I do declare the following to be afull, clear, and exact description of the invention, such as will e11-able others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

Figure 1 of the drawings is a representation of a front view of mycoupler. Fig. 2 is a vertical sectional'view of the same." Fig. 3 is avertical cross-sectional view, and Fig. 4 is a detail view.

"This invention has relation to devices for coupling and uncouplingrailway-cars; and it consists in the construction and novel arrangementof the oblique slidepin and its stops, and

in connection therewith a spring-lever having transverse arms extendingto the sides of the car; the central notch-bearing in the lower lip ofthe mouth of the drawhead, and the curved link pivoted therein; and, incombination with the notched drawhead and curved link, the transversepivot-pin having a square bearing for said curved link, and anoperating-handle, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the draw-bar,which is formed with a flaring mouth, B, in the lower lip, O, of whichis made a notch seat or hearing, D, in the central portion thereof. Inthis notch-bearing is seated a coupling-link, E, which is formed with acurved extension or arm, a, which extends upward to the upper portion ofthe notch, and is provided with a square bearing, 1), through whichpasses a transverse pivot pin, F, which is squared at its centralportion to fit said bearing. The ends or arms of the pin are rounded toform journals, which are seated in bearings c of the draw-head. The headof the pin is perforated at (Z to engage a loop, 6, at the end of ahandle-rod, G, which .is designed to hang downward when not in use. Thishandle-rod is made long enough to extend to the side of the car, ornearly thereto, so that it can be operated easily without going betweenthe cars. The curved extension of the link lies entirely within thenotch of the drawhead when it is not in use, and hangs pendent, so thatit offers no obstruction to the entrance of the link of the draw-head ofan approaching ear. Extending from the cavity of the draw-head upwardand rearward obliquely, but centrally, is aslideway, H, which is formedwith lateral groove-bearings, having terminations or stops it below theupper end of the slideway. I11 the slideway is seated the obliqueslide-pin K, which is laterally flattened, having its greatest breadthfrom front to rear, to provide great strength in the direction ofstrain. In rear, at the lower end of the slidepin, a vertical bearing,7c, is formed, which is designed to engage the coupling-link whenintroduced. The lower end of the slide-pin is beveled in front, asindicated. at Z, so that it will be automatically raised b the link whenit enters the draw-head. The slide-pin is provided with lateral studs orpin-bear ings m, which are designed to engage the groove-bearings g ofthe slideway, and serve to prevent the slide-pin from being forcedupward out of its way or bearing. In the upper end of the slide-pin isformed a perforation, p,

which extends from front to rear, and is designed to receive an arm, I,of the angle-lever L, whereof the transverse arm N extends to the sideof the car, and is provided with a crankarm, 1?. From the other side ofthe ear extends a-similar angle-lever, L, the arm I of which is providedwith a loop-bearing, e, which encircles the arm I of the lever firstdescribed. By operating either of these levers the slide-pin can beraised when it is desiredto uncouple and a chain or rod can be connectedto either of these levers and extended to the top of the car, this beingdesirable on freight-cars. By means of a spring, S, the arms of theangle-levers are held in depressed position, except when raised byoperating said levers by hand. A downward bearing is thus made 011 theslide-pin. A small swinging prop or pendent arm, V, is pivoted to theslide-pin, above the upper surface of the draw-head, and

2 V assess when said slide-pin is raised to its full height I 3. Theoblique slide-pin K, having the verabove the draw-head this prop swiuging d ownward engages the top of the draw-head and holds the slide-pin inraised position. In. order to lower the slide-pin, it is then necessaryto trip the swinging prop. The slide-pin then falls automatically. Asthe coupling link is pendent and out of the way when not in use, thisdraw-head and slide-pin will readily operate in connection with thecommon link of an ordinary draw-bar.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1. The oblique slidepin K, having the vertical rear bearing, k, and theunder beveled front bearing, Z, at its lower end, substantially asspecified.

2. The combination, with the oblique slidepin K, its studs andperforation p, of the slideway H in the draw-bar, having lateralgroove-bearings g, and a spring-lever having transverse arms L N,extending to the sides of the car, substantially as specified.

tical rear bearing, is, the under bevel front bearing, Z, at its lowerend, and thelateral studs m, in combination with the draw-head, havingthe oblique slideway H, provided with lateral grooves g, terminating instops h at their up per ends, all adapted to operate substantially asspecified.

4. The combination, with the draw-head having the notch-seat D andbearing 0, of the curved link E, constructed substantially as described,with the upward extension (0, the

transverse pivot-pin F, having square central bearing for said link, andthe pendent operating-handle, all adapted to operate substantially asand for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT H. DOXVLING.
